I am looking for a decent dedicated server here but i see a lot server with 10mbps port, but what's the difference. I guess the speed will be one of the major differences here... 100mbps is much faster...
What kinda traffic are you looking at? If you receive a million hits a month, I'd suggest 100mbps port.
Just do a bit of math based on averages. Go download netmeter and install. Go to a similar website to the one you're looking to make and navigate around a bit. Look at how much bandwidth you use, average it out. Say it's 20kB/sec. 20k * 8 = 160,000kbps. So a 10mbps line could handle about 62 people at a time before dropping below 20kB/sec for each. If it drops to 10k/sec for each you would double the number of people you can serve.
hrm...well given the example I posted you could handle 62 visitors per given second at 20k/sec. Over a 24 hour period you would have to serve more than 5 million visitors at 20k/sec to make the jump to 100mbps worth it. Of course if you need, say, 40k/sec that cuts the number in half. Or if you have more than 62 visitors within the same time span loading the page at the same instant. Anyway, it's a bit more complicated than "I think it's too much" or "I like it being faster."
I have image hosting site which get over 10.000 uniques/day do you guys think 10mbps unmetered port would be enough?
take a look at your bandwidth graph, if you are using more than 6mbps, 100mbps port would help. Otherwise, 10mbps port is good enough
it depends on u..how many visitors and how many accounts...after it u have to know u want 10mbps or 100mbps
